GAS HELMET Filed Nov. 27, 1931 Patented Dec. 12 1933 GAS HELMET Friedrich Schleich, Stuttgart-Munster, Germany, assignor of one-half to firm Cloetta & Muller, Stuttgart-Munster, Germany Application November 27, 1981, Serial No. 517,723, and in Germany February 28, 1930 2 Claims. (Cl. 128141) A gas helmet for protecting against smoke and heat is known in which the neck part is provided with a strap closure. It has been found in practice that this neck closure is not a sufiicient protection against the penetration of. gas.

This objection is overcome by the gas helmet according to the invention which is characterized in that at the front and rear of the neck part a strap of a certain length is stitched to the material of the helmet, the ends of thefront strap being pulled through eyes fixed on the ends of the rear strap so that, when the ends of the front strap are pulled tight, the material of the helmet is only pulled together on the two sides of the neck part, on those lengths, on which the straps bear loosely against the neck part. The neck part of the helmet has two slots on each side, which are covered by a strip of gas-proof material fixed on the inner side of the neck part and threaded through the ends of the front strap. A lining of soft material such as chamois leather is fixed in the neck part. I

By means of this strap closure and owingto the construction of the neck part of the helmet an absolutely reliable gas-proof closure on the neck is obtained.

An embodiment of the invention is illustrated by way of example in the accompanying drawing in which:

Fig. 1 shows the helmet in front perspective view.

Fig. 2 is a cross section through the neck closure in open condition. a

Fig. 3 is a cross section through the neck'closure in closed condition.

The helmet a consists of gas-proof lined material and is made of two separate parts. seams are rendered gas-proof by rubber coating. A strap 12 is attached to the rear neck portion of the helmet a by seams 'u or by sticking on or by sewing and sticking. Eyes p are fixed on the ends of the strap p. A band q is also attached to the front neck portion of the'helmet a by sewing or sticking or both and has free ends p, on both sides. In the material of the helmet a two slots 1' and r are provided on each side through which the free strap ends 1) are threaded. The strap ends {0' are passed through the slots r in inward direction and through the slots 1 in The outward direction and through the eyes p. A second gas proof layer t is fixed inthe material on the neck portion and covers the slots r and r. The inner cloth layer i may be connected to the material of the helmet by sewing or rubber solu- 66 tion. In this layer t a lining t of chamois leather or the like is arranged so that a tight, snug and soft, comfortable fitting of the material on the neck is obtained. By pulling the ends q of the front strap (1 the material of the helmet is only drawn together on both sides of the neck portion along the length s, on which the straps p, q bear loosely against the neck portion. Owing to the drawing together of the neck portion, folds u are formed in the material, which bear tightly 70 the one on the other so that a gas-proof closure is obtained (Fig. 3). The drawing together of the neck portion of the helmet depends upon the thickness of the neck of the wearer, according to which the fold formation on both sides adjusts itself. Owing to the particular construction of the neck closure, only one fold can form on each side. The strap ends q can be tied or otherwise connected on the front side. External reinforcements :1: are mounted on the slots 7' and r, and 0 secured by sewing or the like to the material of the helmet.

I claim:

1. A gas helmet, comprising in combination,

with the neck portion of the helmet, two straps sewn along a certain length to the material of the helmet one at the front and the other at the rear of said neck portion, and an eye fixed on'each end of said rear strap carrying the ends of said front strap adapted to cooperate with said front straps to form a fold so that on the ends ofsaid front straps being pulled towards the front of the helmet the material of the helmet is drawn together on each side of said neck portion on the length on which said straps bear loosely against said neck portion to form a single large fold on each side of the neck.

2. A gas helmet as specified in claim 1, comprising in combination with the neck portion of the helmet having two slots on each side and the front strap the ends of which are threaded through said slots, a cloth strip on the inner side of said neck portion covering said slots.
